The latest causes of calcium deficiency in cucumber and the main points of calcium supplement

Cucumber is a common vegetable in our life, and calcium deficiency is also a common phenomenon in the planting process, which will seriously affect the yield and quality of cucumber. So what is the cause of cucumber calcium deficiency? How to supplement calcium? Let's learn about it together with Xiaobian.

1. The causes of calcium deficiency in cucumber

1. Calcium deficiency in soil is the main reason for calcium deficiency in cucumber, which often occurs in sandy soil, old vegetable garden, continuous cropping vegetable garden and vegetable garden with low organic matter content.

2, the effective calcium content in the soil is generally low in the soil will not be calcium deficiency phenomenon, mainly dissolved in the soil ammonium ions, potassium ions, sodium ions, magnesium ions and other calcium ions can produce antagonistic effect, thus inhibiting the plant root calcium ions west absorption and utilization, resulting in calcium deficiency.

3. The absorption of calcium by roots is mainly carried out by improving root tips. If the roots grow poorly and the absorption capacity is poor, calcium deficiency will occur.

4, calcium in the plant mobility is poor, in the plant transport is mainly driven by transpiration, so transpiration intensity, the longer the growth time of the organ, the more calcium transport, resulting in less calcium in the upper leaves.

II. Calcium supplementation

Cucumber calcium supplement can prevent and control physiological diseases, increase calcium nutrition, effectively prevent and control various physiological diseases caused by calcium deficiency; it can also improve yield, enhance varieties, calcium can promote root absorption, cell division, and promote carbohydrate and protein synthesis. Calcium can reduce the activity of ethylene synthase, reduce the respiration of radish, inhibit cell senescence, improve the storage and transportation of fruit, in addition, calcium is an important component of cell wall, can increase the hardness of cells and organs, so that fruit hardness increases.

III. Key points of calcium supplementation

1. Organic fertilizer should be added to the base fertilizer. On the basis of phosphorus and potassium, calcium magnesium phosphate, calcium superphosphate, calcium nitrate and other calcium-containing fertilizers should be added to sandy soil. For old vegetable gardens, lime powder can be added to supplement calcium content.

2, foliar fertilizer, can add 1-2 kg of calcium superphosphate per 100 kg of water, Zizania latifolia half an hour later, soak for a period of time, take the above extract spray, can also choose amino acid calcium, calcium humate in the vegetable absorption peak period for spraying.

3. Scientific application of nitrogen and potassium fertilizer, ammonium ion and potassium ion have antagonism with calcium ion, and when nitrogen fertilizer is high, calcium absorption will also be inhibited, so the application of nitrogen and potassium fertilizer should be properly controlled.

4, increase the application of organic fertilizer, organic fertilizer is rich in organic matter and a variety of nutrients required for crop growth, to improve the soil, fertility has an excellent role.

The above is the cucumber calcium deficiency reasons and calcium supplement points introduction, hope to help you, want to know more related knowledge, please pay attention to us.
